Time delay induced synchronization transitions.

<p>Dependence of synchronization parameters (10 samples for each , depicted by black dots) and (the average of s for 10 samples, depicted by red dots) on time delay at . Four distinct parameter regions, i.e., asynchronous region (domain I for small ), transition region (domain II for narrow region of time delay , indicated by grey rectangle), synchronous region (domain III for moderate ) and oscillatory region (domain IV for large , indicated by blue rectangle) are revealed.
